Initially, there were only 86 weeds in the garden. The weeds grew at a rate of 8% each week. The following function represents t
Svetlanka [38]

Answer:

f(x) = 86(1.01)^7x; They grow at approximately the rate of 1% per day.

Step-by-step explanation

86 is the number of weeds at the starting point of the question.

8/7% each day,   7 being the total number of days in the week, the weekly growth 8%:  1 day is 8/7% growth or 1.14% rounded up to 1%

In the original equation the 8% growth was represented by 1.08

Substituting the weekly rate of 8% with the daily rate of 1%, or 1.08 with 1.01 the new function is:

f(x) = 86(1.01)^7x

Which of the following must describe a irrational number? A. a number with a repeating or terminating decimal expansion B. a num
Olenka [21]

Answer:

D.

Step-by-step explanation:

A irrational number can be defined as those numbers which are real but can NOT be expressed in simple fractions. The term 'irrational' means 'a number which can not be expressed in ratio of two integers', 'no ratio.'

<u>When a irrational number is expressed in decimal, the numbers keep on expanding without repeating andd without terminating, which means it keeps on expanding infinitely.</u>

For example, π (pi) is an irrational number. When it is expressed in decimals it keeps on expanding non-repeatedly and unendingly.

Another example of an irrational number is √2.

Thus the correct statement that defines irrational number is option D.
